[IGSTK-Users] Get dimensions from igstkImageSpatialObject

[Luis Ibanez]

Hi Troleif,

Thanks for trying the code and verifying that it worked fine for you.

We added a regression test for it now. It is good to have a calibrated
reference for the display of window levels.

No problem for the confusion. It is better to deal with false positives
than to be too optimistic with the code and let some problems pass
unnoticed.


   Please don't hesitate to let us know if you see
   any other suspicious behavior


      Thanks


         Luis
